Filed: 2003-06-24
Abstract: <P>PROBLEM TO BE SOLVED: To certainly feed sheets separately by one sheet even when friction between the sheets becomes large due to moisture absorption or the like or pasteboards are used as the sheets.  <P>SOLUTION: A document feed section 1 as the sheet feeder comprises a tray 2 and a sheet guide member 3 movable in response to the sheet width.

Therefore, a central part in the sheet width direction is naturally apt to the upside in a projecting shape, and the contact area between the sheets can be extremely reduced at the tip of the highest layer.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
